Most Helpful Girl
I used to not think I was very attractive then a ton of people started telling me I was beautiful and that I should model.
So yes, some attractive girls don't realize they're attractive. I think it's because the media and society put a lot of emphasis on very few types of beauty. So some attractive girls feel outshined and overlook their own beauty beacuse they don't have the looks a majority of people say is the most desirable.
